Research on acoustic environment impact of high-speed railway station waiting hall based on image simulation technology

The poor acoustic environment of the waiting hall of the high-speed railway station will result in poor passenger waiting process experience, and there is currently no research related to reducing the poor acoustic environment of the waiting hall. Based on this, this study studied the factors affecting the acoustic environment of the high-speed rail waiting hall from various aspects and used the image simulation technology to carry out the simulation analysis of the actual situation and focused on the analysis of the sound absorption materials in the waiting hall. At the same time, this study obtained the actual noise situation of the high-speed railway station through data collection and compared and analyzed the passenger experience of the high-speed rail hall under the influence of different factors. In addition to this, the reverberation time of the hall was controlled by establishing a corresponding model for analysis and selection and arrangement of materials. Then, the reverberation time was calculated, and the software is used to simulate the test. Therefore, before the project was completed, the reverberation time was theoretically controlled to a more appropriate range. The research shows that the method provided in this paper has certain effects and can provide theoretical reference for subsequent related research. (C) 2021 THE AUTHORS.
